26/Old Dominion Task Force 3
Primary Objective for 26th/Old Dominion Site
To improve effectiveness and efficiency of snow operation services for the North side of the County in the most environmentally and community sensitive manner feasible, while maintaining existing leaf and mulch operations1. Winter Storm Response Facility
a. Enables faster completion of snow and ice clearing or treatment(gain varies by storm event, but typically results in a 10-15% gain)
b. Provides a cost-effective and higher level of service by reducing deadhead time during treatment
c. Chain shop keeps trucks operational during icy or heavy snow conditions
2. At the same time:a. Maintain Leaf Storage and Mulch Distribution operationsb. Address current site deficiencies including zoning setbacks,
appropriate screening and buffers relative to adjacent uses

26/Old Dominion Task Force 6
Current Operations – Leaf Storage & Mulch Distribution
Leaf Storage includes the collection, storage, and off-site processing during the winter months (Nov.- Feb.)
26th St N. site stores 60% of leaves collected in Arlington's leaf vacuum program (approx. 2,300 tons serving 33 Civic Associations)
Existing site can:• Serve 16 leaf
collection trucks
• Average four loads/day/truck
• Maximum six loads/day/truck
26/Old Dominion Task Force 7
Current Operations – Leaf Storage & Mulch Distribution
Mulch Distribution represents a satellite mulch distribution center for residents throughout the year
26th St N. Site Characteristics:• Approx. 1,000 tons of mulch
delivered to site annually
• Separate bays for wood and leaf mulch; size varies w/ season
• Mulch deliveries vary with season:
• Peak wood mulch demand - July (18 deliveries)
• Peak leaf mulch demand - April (14 deliveries)

26/Old Dominion Task Force 9
Current Operations – Salt Staging and Distribution
Salt Operations include the staging and distribution of salt during each winter and spring (Nov.-Apr.)
1. Winter Operations (Nov.-Apr.):a. Staging for 6,000 Tons of salt
(60% of County inventory) b. Use of up to 24 trucks &
one (1) Loader/Backhoe per any 12-hr shift
c. Portable toilet facility
2. Non-Winter operations (May-Oct.)a. Salt replenishmentb. Equipment and
facility maintenance
26/Old Dominion Task Force 10
Current Operations – Salt Staging and Distribution
Salt Loading and Refilling • A backhoe (pictured) or loader is required to load salt from
storage facility onto trucks• Salt refilling frequency dependent on truck size and storm severity.
o Larger trucks could be as frequent as every 3-6 hourso Smaller trucks could be as frequent as every 1-2 hours

Long-Term Operational Needs - Winter Storm Response
Shift Change Facility - Support Spaces
• Restrooms
• Kitchenette
• Locker Room Storage
• Telecom Room
• Emergency Generator
• Circulation
• Parking
26/Old Dominion Task Force 18
Long-Term Operational Needs - Overall Site
Site planning will need to reserve additional areas to allow for:
Fire Lanes
Ingress & Egress to the site
Large vehicle turning radii
Site security
Zoning Setbacks
Stormwater Management Facilities
Buffering and Screening*
*Site screening and/or buffer space requirements TBD, after placement of major program elements is determined
26/Old Dominion Task Force 19
Long-Term Operational Needs - Program Summary
* Estimated areas are subject to change based on further design, inclusion of screening and buffers, and evaluation of parking alternatives. Site design will iterate with intent of dual-use and opportunities for efficient configuration of site elements.

EXISTING SITE ENVIRONMENTAL
PRACTICES
26/Old Dominion Task Force 21
Existing Site Environmental Practices
• Environmental mitigation measures have been implemented on site to facilitate Leaf Storage & Mulch Distribution along with Salt Operations.
• Both operations require compliance with their respective Stormwater Pollution Prevention Plans (SWPPP) for the defined site use.
• Primary pollutants of concern at this facility include sediment, nutrients, hydrocarbons (fuel, oil), hydraulic fluid, and trash.

Draft PSMP - Land Acquisition Policy (page 139)
Generational or Unique Opportunities: Defined as an acquisition opportunity that, if not acquired at the point of availability, would likely become redeveloped to the point it would never become an opportunity again.
Note: The County’s typical method for acquiring land for creating or expanding parks is to make offers to purchase said properties when they are put on the market for sale.

Draft PSMP – Additional Feedback
Feedback received from the public review process on desired County-wide amenities:
• Pickleball
• Hiking Trails
• Mountain Biking
• Natural Wooded Areas
26/Old Dominion Task Force 33
Draft PSMP - Level of Service (LOS) (page 169)
• No national uniform level of service standards exist for parks or recreational amenities across the country.
• However, there are generally 2 types of standards communities use to analyze service: population-based standards and access standards.
• Both will be updated every 5 years for Arlington County.
Mapped LOS
Indicates, based on geography, where Arlington may need additional/feweramenities or improved accessto those amenities.
Population Based
Indicates the quantity of each amenity Arlington
needs between now and 2035 (verifies whether the
County has a surplus or deficit of any particular
amenity.

Draft PSMP - Arlington Outer Loop (page 83)
• Outer Loop extends access to the north
• Approximately 19-mile loop
• Combination of protected & enhanced routes
• Connects the major trail networks
Note: The County is still receiving feedback on the outer loop and the route may be altered to take advantage of existing transit infrastructure and avoid sensitive environmental areas.
